What Sojourn is and what it is used for

The active substance of Sojourn is sevoflurane, which is a general anesthetic used during surgical procedures and other interventions.
Sojourn is an inhalation general anesthetic administered as a vapor to be inhaled.
Sojourn is used to induce deep sleep (induction of anesthesia) and to maintain it, as well as to relieve pain in patients undergoing surgical procedures (maintenance of anesthesia). If there is no improvement or the patient feels worse, they should consult their doctor.

Important information before using Sojourn

Sojourn should only be administered by trained medical personnel under the supervision of an anesthesiologist or by an anesthesiologist.
When not to use Sojourn and inform your doctor:
if there are medical reasons why the patient should not receive general anesthesia
if the patient has previously been informed that they should not receive general anesthesia
if the patient is allergic (hypersensitive) to sevoflurane or other anesthetics
if the patient or a family member has experienced a condition called malignant hyperthermia (sudden increase in body temperature and severe muscle contractions) during anesthesia
if the patient has liver disease or has previously used general anesthetics, especially if they were administered multiple times in a short period. Some anesthetics may occasionally cause liver disease, which can cause yellowing of the skin and eyes (jaundice).
if the patient has ever experienced QT prolongation (prolongation of a special time interval in the ECG) or torsades de pointes (a specific type of heart rhythm), which may also be associated with QT prolongation. Sometimes sevoflurane can cause these conditions.
if the patient has a tendency to experience seizures or is at risk of seizures
if the patient has a mitochondrial disease.
Warnings and precautions
Before starting treatment with Sojourn, the patient should discuss with their doctor:
if the patient has used general anesthetics in the past, especially if they were administered multiple times in a short period, the risk of liver disease may be increased
if the patient has another disease unrelated to the operation, especially kidney or heart disease, low blood pressure, severe headaches, nausea or vomiting, or Pompe disease in children (a metabolic disorder). Sevoflurane may cause heart rhythm disturbances, which can be severe in some cases.
if the patient has a specific type of muscle weakness (myasthenia gravis), as patients with this disease are very sensitive to drugs that reduce the frequency and depth of breathing.
if the patient has coronary heart disease
if the patient has hypovolemia (reduced blood volume) or is weakened
if the patient has a neuromuscular disease, especially Duchenne muscular dystrophy
if the patient has increased intracranial pressure, e.g. due to head injury or brain tumor
if the patient has experienced seizures or convulsions, as sevoflurane increases the risk of seizures
if the patient is pregnant or breastfeeding
children
if the patient has Down syndrome.
If any of the above circumstances apply to the patient, they should consult their doctor, nurse, or pharmacist. The patient will then require a thorough examination by the doctor and possibly a change of medication.
The following effects may occur during or after administration of Sojourn 100%, liquid for steam inhalation:
During the induction phase, sevoflurane and similar anesthetics (halogenated anesthetics) may cause coughing. This should be taken into account.
As with other anesthetics, sevoflurane may cause mild mood changes for a few days after administration.
Young children under the age of six are more likely to experience acute confusion (delirium) after waking up from anesthesia. Additionally, children under the age of six are more likely to experience agitation/restlessness after waking up from anesthesia.
Sensitive patients may experience a state of excessive metabolic rate (hypermetabolism) of skeletal muscles, leading to high muscle demand for oxygen due to high CO2 levels in the blood (hypercapnia). This can cause muscle stiffness, rapid heart rate (tachycardia), increased breathing rate (tachypnea), blue discoloration of the lips, tongue, skin, and mucous membranes (cyanosis), heart rhythm disturbances (arrhythmia), and/or unstable blood pressure.
In rare cases, the use of inhalation anesthetics has led to increased potassium levels in the blood (hyperkalemia), which can cause heart rhythm disturbances (arrhythmia) and death in children after surgery. This has been reported in patients with neuromuscular diseases, especially Duchenne muscular dystrophy.
Sevoflurane may cause respiratory depression, which can be exacerbated by narcotic premedication or other drugs that cause respiratory depression. Respiratory function should be monitored and supported if necessary.

Sojourn and other medicines

The patient should inform their doctor about the following medicines they are currently taking or have recently taken:
Medicines or active substances contained in the medicines listed below may interact with each other when used concomitantly with Sojourn. Some of these medicines are administered to the patient by the anesthesiologist during surgery, as indicated in the description.
amphetamines (stimulants): used to treat attention deficit hyperactivity disorder (ADHD) or narcolepsy
cardiac medicines, such as adrenaline or epinephrine
beta-adrenergic blockers (e.g. atenolol, propranolol). These are cardiac medicines often used to treat high blood pressure.
alcohol
barbiturates (sleeping pills)
St. John's Wort (a herbal preparation used to treat depression)
constricting medicines (ephedrine): used as decongestants and often contained in cough and cold medicines.
non-selective monoamine oxidase inhibitors (MAOIs) (a group of antidepressant medicines)
calcium antagonists
verapamil (a cardiac medicine used to treat high blood pressure or heart rhythm disorders)
sedatives (benzodiazepines, e.g. diazepam, lorazepam). These are sedatives with a calming effect. They are used when the patient is anxious, e.g. before surgery.
strong painkillers, such as morphine or codeine
muscle relaxants (non-depolarizing, e.g. vecuronium, pancuronium, atracurium, and depolarizing, e.g. succinylcholine): These medicines are used in general anesthesia to relax muscles.
isoniazid, used to treat tuberculosis
isoprenaline

• other anesthetics, e.g. nitrous oxide: This is a medicine used during general anesthesia that induces sleep and relieves pain; propofol, opioids (e.g. alfentanil and sufentanil): These are strong painkillers and are often used during general anesthesia, and sevoflurane may affect their action if they are administered at the same time.

The patient should inform their doctor or nurse about all medicines they are currently taking or have recently taken, as well as any over-the-counter medicines. They should also inform about any herbal medicinal products, vitamins, and minerals they are taking.

Using Sojourn with food and drink

Sojourn, 100%, liquid for steam inhalation, is a medicine that induces and maintains sleep in the patient to allow for surgical procedures. The patient should ask their doctor, surgeon, or anesthesiologist when and what they can eat or drink after waking up from anesthesia.
Pregnancy and breastfeeding
If the patient is pregnant, thinks they may be pregnant, or is breastfeeding, they should inform their doctor or anesthesiologist. It is not known whether sevoflurane or its metabolites pass into breast milk. It is recommended to stop breastfeeding for 48 hours after administration of sevoflurane and discard the milk produced during this period. Sojourn 100% liquid for steam inhalation should not be used in pregnant women unless absolutely necessary.
The use of sevoflurane for anesthesia during cesarean section is safe for both the patient and their child. The safety of sevoflurane during contractions and natural childbirth has not been established. Like other anesthetics, sevoflurane may cause a decrease in respiratory rate in newborns. In this case, the doctor will decide whether sevoflurane can be used.

Driving and using machines

Sojourn, 100%, liquid for steam inhalation, has a significant impact on the ability to drive and use machines. The patient should not drive or operate any machines until their doctor informs them that it is safe.
Receiving general anesthesia may impair the patient's physical and mental abilities for several days. This can impair their ability to perform tasks that require proper concentration. The patient should ask their anesthesiologist when they can safely drive and use machines again.

How to use Sojourn

Sojourn is administered only in a hospital setting by a trained anesthesiologist who will determine the appropriate dose and duration of sevoflurane administration for the patient. The dose will vary depending on the patient's age, weight, type of surgical procedure, and other medicines administered during surgery.
Sojourn in the form of a liquid turns into a gas in a vaporizer and is inhaled by the patient for anesthesia.
It can be used to induce sleep in the patient before surgery or, if the patient has been put to sleep by injection, to maintain anesthesia during surgery.
When the anesthesiologist stops administering Sojourn to the patient, the patient will wake up within a few minutes.
In case of any further doubts about the use of this medicine, the patient should consult their anesthesiologist or nurse.
Using more than the recommended dose of Sojourn
Sojourn will be administered to the patient by medical personnel, and it is unlikely that the patient will receive too much Sojourn. If the patient receives too much Sojourn, the anesthesiologist will take the necessary actions.

Possible side effects

Like all medicines, Sojourn can cause side effects, although not everybody gets them. The patient should immediately inform their doctor, nurse, or anesthesiologist if they do not feel well.

Severe, rare side effects (can be life-threatening):

• anaphylactic or anaphylactoid reactions (see "Side effects of unknown frequency" below)

The following side effects are severe and may require immediate medical attention. During anesthesia, the patient is under medical supervision and will receive immediate help if necessary.

The patient should immediately inform their doctor or nurse:

if they have an allergic reaction, which can be severe, with swelling of the face, tongue, and throat, and difficulty breathing.
if they experience malignant hyperthermia (very high fever), which requires intensive therapy and can be life-threatening. This condition can occur in any member of the patient's family.
if they have increased potassium levels in the blood (hyperkalemia), which can cause heart rhythm disturbances. Hyperkalemia can lead to death, especially in children after surgery. Such cases have been reported in patients with neuromuscular diseases, especially Duchenne muscular dystrophy.

The patient should inform their doctor or nurse in case of:
